A filter is a resource that is assigned to an MNI. Positive or negative filters control some types of traffic through a specified MNI subnetwork. You add filters to a SafeLinx Server, but they apply to mobile access services only.
The filter criteria that you use in a filter depends on the packet type. A filter can be defined to block packets or to pass packets according to the specified criteria. The SafeLinx Administrator includes a set of default filters and a filter group that is called Default Filters.
You can assign filters to transport profiles to control data flow from the SafeLinx Client to mobile access services.
